... and human health. The water, sanitation, and hygiene sector has recognized that valorization of treated fecal sludge could offset the upfront cost of treatment by using it as a fuel source. The few quantitative studies on fecal sludge fuel published to date have focused on heating value, moisture, ash...

... effective systems such as decentralized wastewatertreatment systems (DEWATS) to be developed. These involve the use of anaerobic baffled reactors (ABR). Wang et al. (2004) defined the ABR as a closed tank with series of hanging and standing baffles which allow wastewater to flow under and over them...

..., a used-water facility, owned and operated by a sanitation district, may provide source water to an advanced treatment facility, owned and operated by a municipal water district. The sanitation district's primary mission is to satisfy the regulatory requirements associated with the disposal of...

...K. Jesitha; P. S. Harikumar Abstract A bioreactor system that consisted of Pseudomonas fluorescens cells immobilised in calcium-alginate beads was utilised to remediate endosulphan contaminated water and soil. A packed bed reactor system was designed for the bio-degradation of endosulphan in...

.... Additionally, not all tenants cleaned the toilet when they were supposed to, which also led to conflict among tenants and, in a few cases, between landlords and tenants. Tenants also reported conflict as a result of personality clashes, treatment of children, noise pollution and solid waste disposal, where...

... individual adsorption were 63.44 m²/g, 56.18 m²/g, and 75.41 m²/g, which were smaller than those (97.70 m²/g, 87.56 m²/g, 86.23 m²/g) of the corresponding starting MNZVI/CNTs-OH. The reusability of adsorbents is of great importance as a cost-effective process in watertreatment. In order to investigate...

... Districts have produced water reuse fact sheets targeted to the community to improve public perception of recycled water use. In 1943, the California Water Code defined recycled water as the ‘result of treatment of waste, [which] is suitably considered a valuable resource’ ( State of California 1943 ). In...

... have more efficient use of water resources and a smaller specific volume of wastewater requiring disposal and/or treatment and show better data reporting than smaller ones. Wineries often produce large amounts of wastewater and the seasonal nature of the winemaking industry poses problems for...

... treatment are uncertain. Figure 2 Graphical representation of the occurrence of the different microorganisms studied, (a) according to distance to the river and water source and (b) for the three types of water sources investigated: river, unprotected wells and protected wells. The logarithmic regressions...

... Figure 1 for a schematic of the types of water systems that households access. These constraints appear through either cost and/or time investments in storage, additional water sources and treatment methods to ensure water is available for different tasks each week. Although wealth, household location...

... increasing concerns of water scarcity and environmental pollution, a new trend has emerged for decentralized and source-separated approaches to processing wastewater as a resource. Source-separation of wastewater involves separate collection and treatment of the different domestic wastewater streams. About...

... in wastewater treatment. Scientific studies around the world have shown that these compounds generate the adverse effect of high acidity in the treated water ( Cooke et al. 1986 ) and may become precursors in the etiopathogenesis of neuronal disorders such as Alzheimer's disease ( Teh et al. 2016...
